I '0 all whom it may concern Be it known that I, Gnoncn F. KENDALL, a citizen of the United States,-residing in the city and county'of New York, State of New York, have invented a new and useful Distillation Retort and Separating Tanks, of which the following is a specification.

My invention relates to an apparatus for the treatment of solid material or any material that becomes volatile under heat and further enables said volatile material to be extracted from the retort in which it is treated and be precipitated in a plurality of tanks according to the specific gravity of the material volatilized.

A further object of my invention is to provide an apparatus which enables the treated material and the volatile products to be extracted without loss and without the creation of any fumes.

Another object of my invention is to provide an apparatus, which permits the expulsion of all air from the retort in the treatment of the materials contained therein to prevent oxidizing, and I also provide means for cooling the material in the re tort after distillation thereof, so that the product can be extracted from the retort without endangering loss by combustion.

A still further object of myzinvention is to provide an apparatus of this character,

wherein a novel construction of burner is employed to produce an eilicient combustion in relation to the retort containing the material to be distilled.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same will give in practice 'satisfactory'and re liable results, although it is to be understood that the various'instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described. Figure 1 represents a side elevation, partly in section, of a distillation apparatus embodying my invention.

Fig. 2 represents a vertical transverse section, partly in elevation, through the furnace showing another embodiment of my invention.

Fig. 3 represents a View similar to Fig. 2,

- Referring to the drawings showing a still further embodiment of my invention. r

' Similar numerals of reference indicate corresponding parts in the figures.

Referring to the embodiment of my invention in F ig. 1, 1 designatesa furnace having a combustion chamber 2, in which IS located the retort 3 supported in the front and rear walls 4: and 5 of the furnace. 6 and 7 designate angular members or brackets secured to the front and rear walls land 5 of the furnace'for effectively sup: porting said retort, which is preferably composed of a refractory material, such as fire clay capable of standing high heat and internal pressure "without cracking and enabling the material to be internally cooled without cracking the outer shell.

8 designates a manhole for the reception of carbonaceous material, such as bituminous coal into the retort, wherein the material is'subject to distillation. 9 and 10 designate manholes for the extraction of solid products and 11 designates an outlet for drawing off the liquids from the retort, such as tar, creosote and carbolic acid, etc, after distillation of the carbonaceous materials.

These manholes are provided with steam tight closures 12, 13 and 14:, so as to her- .metically seal the interior and subject the material contained inthe retort to the action of the steam employed for purposes of distillation.

Combustion in the combustion chamber 2 is preferably produced by gas of the producer type fed into a plurality of burners 15 through the inlet pipe 16 controlled by the valve 17. The burners 15 consist of longitudinal tubes 18 perforated, as at 19, for the discharge of gas for combustion purposes. 20 designates regulator caps for closing the ends of the burners. These regulator caps have openings adjustably arranged in relation to openings in the burner tubes for the admission of preheated air into the burners to mix with the gas. Intermediate of these regulator caps 20, Ts 21 are arranged which are provided with downwardly threaded. extensions 22 screwing into the blocks 23 secured to the perforated partition 24. In this manner, the burners 15 may be adjusted vertically in relation to the bottom of the retort'according to the class of material to'be distilled and the various methods of distillation employed.

A pilot light 25 supplied with gas from without is located in the combustion chamber adjacent the burners for lighting the burners 15. Access to the combustion chambe]? 2 and to theburners 15 located therein is had through the fire door 26 in front wall. 4 of the furnace 1.

27 designates a chimney for the discharge of used gases from the furnace.

Below the partition 24, an air chamber 27 is located for preheating air prior to its discharge through the perforations 28 of the partition, 24 into the combustion chamber 2 to support combustion of the gases. 29 designates an air inlet pipe through which air is fed into the air chamber 27, the flow 'of air through this pipe into the air chamber 27 being controlled by the valve. 30.

31 designates a steam supply pipe provided with the valve 32 for the control of a continuous or intermittent injection of steam preferably in a superheated condition into the retort 3.

The steam in a highly superheated condition passes through the retort 3 carrying therewith the volatile gases of distillation into apipe 33 provided with the depending tap pipes 34, 35 and 36 communicating with a plurality of condensationtanks 37, 38 and 39 water jacketed as shown at 40 and provided with suitable means for determining the quantity of material contained therein. 41, 42 and43 designate outlet valves for drawing off the contents contained in the condensation tanks 37, 3S and 39.

The pipe 33 is plugged at 44 and provided with the valves 45, 46 and 47 for directing the volatile gases into'the-desired condensation tanks according to the specific gravity thereof.

48 designates a pipe provided with the valve 49 for conducting wet steam into the pipe 31, which flows thence into the retort 3 for application to the sol-ids after distillation preparatory tothe removal of said solids from said retort.

In Fig. 2, another embodiment of my invention is shown, wherein is represented a vertical transverse sectional view, partly in elevation, of the furnace 50 of which 51 is the combustion chamber. 52 designates a retort located in the combustion chamber 51.

This retort is ,provi-ded with the longitu" di-nal tongues 53 embedded in and supported by the side wal1s 55 and 56. 57 designates a manhole for the reception of the carbonaceous material into the retort, said manhole being provided with the steam tight cover-58.

59 designates a manhole for the removal of the solid products after the distillation thereof. 7

60 designates the inlet pipe for the injection of a continuous or intermittent stream of superheated steam into the retort. 1

Combustion in the combustion chamberbl is preferably produced by burners 61, which 7 consists of a plurality of perforated transverse tubes 62 of a curvature conforming with the contour o fthe retort 52. The ends of the tubes 62 are closed by the regulator caps 63, whileintermediate these caps, Ts 64 are arranged, theburner tubes 62 and-the threaded extensions 65 being adapted to be screwed into the blocks 66 secured to the perforated partition 67, for the vertical adjustment of the burners in relation to the retortj Gas is supplied to the burners'61 by the inlet pipe 77 provided with the valve 78 for controlling the supply of gas. A pilot light 68 is located in the combustion chamber adjacent the burners for lighting the burners.

69 designates a chimney for the discharge of used gases from the combustion chamber. Air for-supporting combustion of-the gases is supplied to the combustion chamber from the air chamber 70 through the perfora" tions 71 in the partition 67. 72 designates an inlet pipe for the supply of air into the air chamber70. V

In Fig. 3, a still further embodiment of my invent-ion is shown, in which isrepresented a view similar to that of Fig. 2, wherein a d fferent method is used for pro ducing combustion by gas, which consists n arranging several layers of spherical ob- ]8.CtS 73, on the perforated partition 67 These spheres 73 are preferably composed of the clay or other refractory material to prevent burning out and allow for the ready removal and replacing of thesame. f i

The gas chamber 74 below the perforated part tion 67 isprovided with the inlets 75 and 7 6 for the supply of gasand air. With an arrangement of this character it can readily be seen that an. even fire surfacejis produced in the combustion chamber. It

' will be of course understood that the spheres 73 can be arranged in any suitable manner to produce the best combustion results in relafrom the solids in the retort 32 and from an admixture with the superheated steam.

The admixture of superheated steam and volatile gases is then carried by the continuous flow of steam into the distributing pipe where the gases, according to their specific gravity, are precipitated into the respective condensation tanks 37, 3S and 39.

The remaining solids produced in the retort are then subjected to wet steam from the pipe 48 to allow for the ready removal of the same through the manholes 9 and 10 and the outlet 11.

The burners 18, 61 may be readily adjusted and arranged in relation to their respective retorts to produce the most efficient combustion.

it will now be apparent that I have devised a novel and useful distillation retort and separating tanks, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and While I have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. An apparatus of the character described, comprising a combustion chamber, a material containing retort therein, an air chamber, a perforated partition separating said combustion chamber from said air chamber, burners adjustably supported on said partition in said combustion chamber, regulator caps on said burners for the admission of preheated air into said burners, and a gas supply pipe communicating with said burners from Without the combustion chamher.
